柱未發現：在「字段列表」

Question

1054未知列「圖像」我有模型的文章，文件組，文件。

時節省用圖像的新文章，它會顯示這個錯誤：

{"exception":"Illuminate\Database\QueryException","message":"SQLSTATE[42S22]: Column not found: 1054 Unknown column 'image' in 'field list' (SQL: insert into articles (title , text , like_count , view_count , comment_count , image , web_image , updated_at , created_at) values (dsvdscdscdscsdcdsc, sacsaxasxsaxsaxsaxsaxsax, 0, 0, 0, 11, 13989, 2017-06-27 15:40:49, 2017-06-27 15:40:49))","trace":[{"file":"/var/www/laravel/www/vendor/laravel/framework/src/Illuminate/Database/Connection.php","line":726,"function":"runQueryCallback","class":"Illuminate\Database\Connection","type":"->","args":["insert into articles (title , text , like_count , view_count , comment_count , image , web_image , updated_at , created_at) values (?, ?, ?, ?, ?, ?, ?, ?, ?)",..................

型號/ Article.php

namespace App\Models; 

use Illuminate\Database\Eloquent\Model; 

class Article extends Model 
{ 
    protected $guarded = ['id']; 
    protected $with = ['image']; 

    public function image() 
    { 
     return $this->belongsTo('App\Models\Filegroup', 'image_id'); 
    } 
} 

型號/ FileGroup.php

use Illuminate\Database\Eloquent\Model; 

class Filegroup extends Model 
{ 
    protected $table = 'file_groups'; 

    protected $with = ['files', 'name']; 

    protected $guarded = ['id']; 

    /** 
    * One-to-Many relations with SiteString. 
    * 
    * @foreignModel SiteString 
    * @return \Illuminate\Database\Eloquent\Relations\BelongsTo 
    */ 
    public function name() 
    { 
     return $this->belongsTo('App\Models\SiteString', 'name_id'); 
    } 

    /** 
    * Many-to-Many relations with File. 
    * 
    * @foreignModel File 
    * @return \Illuminate\Database\Eloquent\Relations\HasMany 
    */ 
    public function files() 
    { 
     return $this->hasMany('App\Models\File', 'filegroup_id'); 
    } 
} 

個型號/ file.php

namespace App\Models; 

use Illuminate\Database\Eloquent\Model; 

class File extends Model 
{ 
    protected $table = 'files'; 

    protected $fillable = [ 
     'mimi_type', 
     'path', 
     'width', 
     'height', 
     'size' 
    ]; 

    /** 
    * One-to-Many inverse relations with Filegroup. 
    * 
    * @foreignModel Filegroup 
    * @return \Illuminate\Database\Eloquent\Relations\BelongsTo 
    */ 
    public function group() 
    { 
     return $this->belongsTo('App\Models\Filegroup', 'filegroup_id'); 
    } 
} 

表文章與移民創建：

class CreateArticlesTable extends Migration 
{ 
    /** 
    * Run the migrations. 
    * 
    * @return void 
    */ 
    public function up() 
    { 
     Schema::create('articles', function (Blueprint $table) { 
      $table->increments('id'); 
      $table->integer('image_id'); 
      $table->text('text'); 
      $table->string('title'); 
      $table->integer('like_count'); 
      $table->integer('view_count'); 
      $table->integer('comment_count'); 
      $table->timestamps(); 
     }); 
    } 

    /** 
    * Reverse the migrations. 
    * 
    * @return void 
    */ 
    public function down() 
    { 
     Schema::dropIfExists('articles'); 
    } 
}

當你使用一個模型$guarded屬性，而不是$fillable它會嘗試插入的屬性的每個值陣列模型的。更多關於這裏：https://laravel.com/docs/5.4/eloquent#mass-assignment

您可以確保屬性，你分配給你的文章模型中的數組只包含有相應的數據庫列，或者您可以切換到$fillable像這樣的屬性：

protected $fillable = [ 
    'image_id', 
    'text', 
    'title', 
    'like_count', 
    'view_count', 
    'comment_count', 
];
